Hi,

I am trying to understand what path is executed in GCC from parsing a C
expression (in a global variable declaration) to the value in DECL_INITIAL.
At the moment, I have annotated a tree during parsing. I have another
debugging pass that looks for this tree in subsequent passes. The
annotation persists if the tree is inside a function body. However, if the
tree is in a global variable initialization (i.e., DECL_INITIAL), then I am
unable to see the annotation even when placing the debugging pass at the
beginning of passes.def.

Can someone provide a little bit of guidance?

Thanks!
